AUTOMATIC SELF PLUMBING AND OILING PUMP-HEAD.

Specication of Letters Patent.

Application tiled February 2, 1916. Serial No. 75,853.

To all whom z't may concern:

Be it known that we, FENN H. PALMER and SAMUEL C. CARTER, citizens of t-he United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented an Automatic Self Plumbing and Oiling Pump-Head, of which the following is a specification.

This invention relates to ump-heads for use in a propeller pump in W ich the propellers are mounted on a Shaft that extends down into pump casing through which the water is impelled from a well or other source of supply. The shafts-of such propeller pumps are rotated at high speed and su port the column of water being pumped.

t is very important and necessary that the shaft of such a ump shall be perfectly plumb and that it s all be in perfect alinement with the pump casing, and that the supporting 4bearing therefor shall be perfectly level and shall be kept perfectly 1ubricated in order to prevent 1t from running hot.

An object of this invention is to so con-- struct a pump-head that it will be automatically plumbed and the bearing will be held level, and the pump shaft will be automatically alined wlth the pump casing by the action of gravity irrespective of an un-4 level condition of the base.

That is to say, an object 1s to make provision where'by it is not important that the base of the pump head shall be level, and whereby the bearing support or body of the pump head will be invariably brought to true position upon simply placing said body or. support on the pump head base.

Further objects are to make provision whereby the belt pull is borne by radlal bearings; to make it .easy to change the pulleys to meet various conditions; to allow easy removal of the belt; to leave the pump shaft free from all vside strain making a full floating drive-shaft; to make it impossible for water to enter the 'bearinor through dei'ective packing; and to avoic ailfecting the operation of the pump by a leak at the bearing.

An o'bjec-t of the invention is to make provision whereby the bearing| of the propeller shaft is made to support the weight of the shaft and also the thrust of the belt upon the pulley in the most eiiicient way and to provide a superior oiling device that is positive in its operation and that will conserve the oil, prevent its evaporation and loss by splashing or leakage and will also protect the bearing from dust and rust.

Other objects of the invention are simplicity, cheapness and compactness, and superior ease and convenience of installation and operation.

A further object of the invention is to provide a full floating shaft for propeller pumps.

The accompanying drawing illustrates the invention.

Figure 1 is a vertical axial section cen trally through the discharge bend.

Fig. 2 is a plan in section on line 2--2 just above the discharge bend.

This novel pump head comprises a body 1 having abent passage 2 therethrough and also provided with a 1foot 3 and adapted to rest on the margin 4 of the orifice 5 in a support or base 6 and also adapted to receive a punrp casing 7, which 1s fixed as indicated by the threaded joint 8 in the lower end of the bent passage 2. Preferably the joint at 3, 4, between the body 1 and the support 6 is in the nature of a ball-andsocket joint; the foot 3 forming the ball, and the margin 4 forming the socket of the joint; the pivotal support thus formed allows the body 1 to adjust itself on the support 6 by the weight of the depending pump casing 7. Said body 1 is also provided with a shaft bore 9 axially alined with the orifice 5 and extending through the upper wall 10 of thebent passage 2. Said bore 9 terminates above said wall in a stuifing-box 11 formed on the upper wall 10 and provided with a gland 12. Supporting means whch may be in the form of standards 13, 14, are fixed to the body, the same being upper extensions of the upper wall 10 of the body, and at the upper end of said supporting means a bearing support or step 15 is mounted, the same being constructed as a web having a hole 16 therethrough which may be threaded to receive a stand pipe 17.

An annular wall 1S extending up from the web 15 and terminating in a flange 19 forms the lower end of the housing and the (ill bottom of an oil reservoir into which oil may be introduced through an oil supply pipe 2l screwed through said wall 'i8 at the bottom of the reservoir 20 and extending" upward and terminating below the level ot the upper end or the stand pipe l., The housing, is continued upward and the oil reservoir is completed by a hollow column 22 provided with an outer flange 23 to rest on flange 19 and an inner depending; collar 24 to fit inside the wall i8. Said column is fixed to the body by bolts and nuts 25 in flanges 19 and 23.

it hollow rotor 26 is suitably mounted upon a bearing 52'?- that is carried by the support l5. fl shalt 28 is connected. to the rotor by a lrey and key-way 29 and by a nut 3@ screwed down upon a washer 3l on the upper` end ot a hub 32 et said rotor.,

Said rotor is provided at its hub with a flange 33 which a pulley 34- is dried, said pulley preferably being provided at its uper end with a head il? having orifice 38 oi suiiicient diameter to pass down over the hub 329 so that the pulley head 3T may rest upon the flange to which said hub .is secured by cap screws 39. Lateral n ings l0 and il arranged tween the rotor and the inner walls orc tb llow hous in@` column 22. @aid rotor is liz* to ends above a toot Ll2 supp by an anti-'friction bearing carried by bearing` support or "lhe bearings common annular bearings and surround the standpipe l? which extends up through the toot l2 and said beafngs..

Said anti-friction bearing1 lor the 'ioot is shown as4 made or the loose annular cup or adjusting washer l the race cone l-7 antidriction balls in the race-way oil the cone del., and the upper race-way ring lli restingr1 on the anti-friction balls 5, said ring lo eing mounted in an annular recess d? `pio vided therefor in the toot The hollow column 22 is provided at its upper end with an annular cap that snugly its around the hub 52 below 33 and that is provided with annular groove i9 which is cut into the ot the central oriiice ont said annular cap e8? so 'that any splash of o om below the cap will be intercepted the channel l@ and returned downward by gravity 'l he bearings and are supported by spacers and 5L the lower spacer 50 resting on the upper side or the 'oot l2 to support the inner race-way 52 oi the ball bearingeO and the upper spacer 5l being a sleeve carried by the annular bearirgS d0 to support the inner race-way 53 ot d e upper ball bearing 4l.

The oil supply pipe @l is' provided at upper end with a closure as the screw cap The body l is provided with a' shoulder shown in the drawing as follows: rlhe coll brust bearremote to receive clamp means 56 that engage t body and may be adjusted on the base li and secured thereto by suitable means as the clamp screws 57..

The shaft 28 may terminate inside the passage Q; and its lower end is provided with a coupling collar 58 fixed thereto by the pin 59 and projecting down below the lower end of the Shaft 28 and adapted to receive the upper pump shaft section 60, which may be fastened thereto by the pin 6l.

The pump head may be assembled. as er 58 may be xed to one end of the shaft 28 by the pin 59. The stand-pipe 17 may be screwed into the hole 16, and the shalt 28 be passed through the bore 9, the gland 1%' the hole i6 and the standpipe l?. rlhe head may then be stood on its lower end. it and the collar 58 resting on a support. notv shown, and then the several parts ot' Jthe lower thrust bearing1 27 may be assembled inside the reser voir 20 in an obvious way.

rlhe dust cap and oil retainer d8, the annular bearingll, spacer 5l, annular bearing l0 and spacer 50 will be slipped onto the reduced lower end oi the rotor Q6. The hollow column 22 is then put into place and the toot d2 is then screwed into place on the rotor. rlllhe rotor will then be put in place on the shalt with the toot l2 resting on the lower thrust bearing4 27. Then the hollow column 22 maybe secured by the bolts and nuts 25, thus completingr the reservoir con* taining ano surrounding the stand-pipe and adapted to contain the annular bearings and oil for lubricating the saine. The hey 29 beingn applied between the shaft 28 and the tor? said shaft is adapted torotate with rotor. n hen the washer 3l and nut 3U rn be applied and the nut screwed home, which the pulley is brought into positie. i. the hub 82 and is lifted to the hub flange f by the cap screws 39.

The support 6 is prepared ready to rec body7 but is preferably shiiiped to t place ciZ use without connecting the bo 7. thereto.

.ltthe well or other place of use the 't 6 is placed over the well the casing and s...

with propeller-s, not shown? are lowered joint by joint into the well in the usual way, and the parts are supported by the elevators7 shown. 'llhen the body and housing shalt 28 are brought into position to a the sha'lt 28 to be connected to the i shat't section 80.

Then the body and shaft are lowered auf the body is brought to the casingand sore thereon. Then the body is lowered until ball-like 'loot 3 rests in the socket or sea., therefor.

lhe gland l2 is always perfectly arcos-- sible for tightening the stufling boxl to prevent leakage.

The weight of the depending casing brings the body and the housing and bearings into plumb and the weight of the shaft holds the shaft in true alinement with the casing and thereupon the clamp means 56 may be applied and fixed in place by the clarmp screws 57 and the pump is ready to receive the belt, not shown, and put into operation.A

It is understood that any other suitable means to rotate the shaft may be substituted for the pulley without altering other features of the invention and that any form of spout or conduit may be connected to the outlet of the passage 2.
